A good marriage is characterized by a process of constant give and take, and constant adaptation to ever-changing circumstances, always leavened by good will. Similarly, to get better economic policy, economists and political types must be joined together in a lasting union—not in a series of one-night stands. They must interact regularly, with each understanding the other’s comparative advantage. To be sure, these will be arranged marriages founded on convenience, not romances based on love. But if we can increase the frequency and durability of such marriages, and limit divorces, George Stigler will have been proven wrong and Don Patinkin will have been proven right.
